Model: LY
Coal Consumption: 1.2-6.5
Kiln Type: Φ1.9-Φ4
Installation: Horizontal/Suspension
1. Reasonable structure design, fire adjustment easily, not only adjustment air volume of axial air, swirling air, but also adjustment outlet section area of axial air ,swirling air and coal air, to reach the goal of change outlet air speed of burner, to ensure fuel burning normally;
2. Less use of primary air, and coal air mix with primary air, secondary air fully, make burning complete, to reduce coal consumption effective;
3. Nozzle is made of special material, heat resistance and replacing easily;
4. Fire cover forming bowleffect, there is not high swirl with fire at beginning, to avoid the peak value of temperature, make the fire temperature distribute uniform and reasonable;
5. Because the combustion air mix pulverized coal fully, the burning is fast and safety, CO and NOX content from kiln tail exit gas are reduced, in favor of equipment operation safety and realize environmentally friendly production;
6. Flange connection for each air pipe of burner, remove and maintenance easily;
7. Adaptable for coal quality, burning low quality coal.
Pulverized coal burner is the key equipment of calcination system in metallurgical, chemical, cement, quicklime rotary kiln, its performance and operation relate to product quality, capacity, energy consumption, environment and so on. Our company design pulverized coal burner is according to different kiln type, different feature of pulverized coal and different technical conditions, with typical structure and reasonable technical parameters, ensuring the pulverized coal, primary air, secondary air mix fully, make high burning efficiency, larger heat intensity, better fire shape and easy control, its widely used in various dry and wet cement rotary kiln, steel sintering pellet rotary kiln, lime rotary kiln, chemical rotary kiln, alumina clinker rotary kiln, power plant boiler and so on.

Pulverized coal burner is main consist of pipes, nozzle, metal bellow compensator, butterfly valve, pressure measuring, protect layer and so on. The main structure characteristics as below:
1. Pipes
From outside to center is axial air channel, swirling air channel, coal air channel, center air channel and firing channel separately, the firing channel is for firing, so it’s called four channel.
2. Nozzle
It’s made of special material, the outlet cross section area of axial air, swirling air and coal air can be adjusted, to adjust the ejection speed of each channel. The whole set nozzle is key part of ensure flame shape.
3. Axial air (swirling air) metal bellow compensator
Axial air (swirling air) metal bellow compensator is key part to connect inner and outer channel of axial(swirling) air, sealing and adjust flame shape.
4. Butterfly valve
Adjustment air volume.
5. Pressure measuring
Display the ejection speed of air from burner.
6. Protect layer
The refractory castables, poured by user
